Fas Drill® SVB Squeeze Packers

The Fas Drill® SVB (Sliding Valve Brass) Packer has a stinger-operated sliding valve that holds pressure from both directions. The sliding valve is opened and closed with workstring manipulation. When weight is placed on the set packer, the sliding valve opens. When pipe weight is lifted from the packer and the stinger is removed from the packer bore, the sliding valve closes, which isolates cement below the packer from the pressure and fluid above the packer.

The Fas Drill® SVB Squeeze Packer is designed for use at temperatures ranging from 50 to 250°F (10 to 121°C), and differential pressures up to 5,000 psi (34 474 kPa). The packer has minimal ferrous metal content, which allows for easy drillout.

A customer in New Mexico was performing a two-stage, cement job for a
9 5/8-in. casing string, but, during the first cement stage all returns were
lost. Whether due to a natural fracture in the formation or just a
high-permeability, low-pressure zone, the operator was now faced with
a difficult cement squeeze job to shut off the thief zone and allow cement
to reach the surface as per local regulatory requirements.
